To 41/ whom it may concern: Be it known that NEY, a citizen of th andState of New Jersey, have tain new and useful Writing Machines, of whichspecification.

his invention relates to type-writing mnchines, particularly those ofthe front-strike class,- and its object is to improve the key touch andto sirnplif actions.

My invention consists in certain feature of construction andcombinutimis of devices, which will be l'zercinafter fully set forth,and particularly pointed out in claims.
